. v To all whom it may concern:

Be it known that I, MERTON D. MANsUR, citizen of the United States,residing at Ashland, in the county of vAroostook and State ofMaine, haveinvented certain new and useful Improvements in I-Iasp -Fasteners, of

which the following is a specification.

This invention comprehends certain new and useful improvements in thattype of fastener which embodies a hasp, a keeper or staple therefor, anda lock or latch designed to secure the hasp to its keeper, and theinvention has for its object an improved construction of hasp lock ofthis character which will be durable and simple andV efficient inoperation, and in which the parts are so arranged that the operation ofswinging the hasp over upon the staple will effect the shooting of thelatch into the staple to lock the hasp thereto, the manual releasing ofthe latch from the staple automatically effecting the casting off of thehasp therefrom.

lVith this and other objects in view as will more fully appear as thedescription proceeds, the invention consists in certain constructions,arrangements, and combinations of the parts that I shall hereinafterfully describe and claim.

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawings, in which:

Figure 1 is a pers ective view of my improved hasp lock in c osed orlocked position; Fig. 2 is a similar view with the parts detached andopen; Fig. 3 is a transverse sectional view of the device in unlockedposition Fig. 4 is a similar view of the device locked; and, Fig. 5 is afront elevation.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

While it is clear that my invention is applicable broadly to fastentogether any two parts, for the purpose of illustration only,

have selected a box, or any other receptacle with a lid to illustratethe application and operation of my improved hasp lock.

Referring to the drawing, the numeral 1 designates the lid of any suchreceptacle, and 2 the body thereof.

3 designates a strap which is secured by rivets or similar fasteningdevices to the lid 1, and 4 designates the hasp which is hinged,

as shown, to the attaching stra 3 and which is formed with a longitudinaly extending slot 5, and an arched guard 6 extending over said slot, soas to protect the operators iingers in the o eration of the lock.

To the bo y 2 or other part to be fastened, a base plate 7 is riveted,or otherwise secured, and a keeper 8, which, in the present instance, isin the form of a sta le and designed to coact with the slot 5, is ormedon or secured to the base plate, as shown. A cast-olf 9 which, in thepresent instance, is in the form of a flat or leaf spring is`secured atone end to the base plate 7 and extends towards and in line with thehasp 4 with its free end normally spaced from the face of the baseplate. Such end of the cast-off 9 is formed with a slot 10 through whichthe staple 8 projects.

The free end of the cast-off 9 is provided at one side of the slot 10with a bar 11, and a detent 12 is pivotally connected at one end to saidbar and projects laterally from 'the cast-o, as shown. The detent 12 isformed between its ends with a ridge or shoulder 13 designed forengagement with the laterally extending tongue 14 formed on one end of aspring latch 15. This latch in the present instance is formed of asingle strip of suitably strong spring wire coiled between its ends, asshown, and mounted and held in a pocket 16 provided on the base plate,the open side of the pocket facing the staple. The free end of thespring latch 15 is also formed with a nger piece 17 for the manipulationof the latch.

In describing the operation of my improved hasp lock, or fasteningdevice, let it be assumed that the tongue 14 has been retracted from thestaple and moved outwardly until it is caught by the" shoulder 13 of thedetent 12. Y The latch will thus be held in an inoperative positionbythe detent, so long as the hasp is in open position. Upon the movementof the hasp over upon the staple or keeper 8, the o erator will pressinwardly.v upon the free en of the hasp and this will manifestly eHectthe depression of the free end of the cast-off 9 so as to rock thedetent inwardly and free the latter from the tongue of the latch 15,whereupon the said tongue will snap through the staple and securely lockthe hasp. In connection with this part of the operation, it is to benoted that the shoulder 13 on the detent is so spaced from the staplethat the free end of the hasp on one will eiiect the inward movement ofthe detent as a whole so as to permit the tongue to ride over theshoulder and snap through the staple over the end of the hasp. In thisoperation, the operators fingers are protected Jfrom injury by thespring action of the latch, through the instrumentality of the guard 6which extends over the staple, as shown.

In order now to release the hasp, it is only necessary to retract thelatch from the staple, whereupon, the depressed free end of the cast-oilwill be permitted to exert its tension and automatically swing the haspaway from the staple, while, at the same time such movement of thecast-oil will carry the detent away from the base plate and effect theengagement of the shoulder with the end of the tongue 14 of the latch assoon as the tongue has been sprung outwardly beyond the shoulder. Thusthe tongue will be automatically caught by the detent and held in aninoperative position away from the staple until the hasp has beenpressed again upon the cast-off.

From the foregoing description, in connection with the accompanyingdrawings, it will be seen that 1 have provided a very simple, durableand efficient construction of hasp lock in which the spring-shot latchto lock the has to thekeeper or staple is automatically he d restrainedin an inoperative position, until the hasp has been moved over intoengagement with the keeper and that such movement of the hasp willeffect the automatic release of the latch from the detent and permit thelatch to shoot home into engagement with the keeper to lock the haspsecurely thereto. 1t will also be seen that in the reverse movement ofthe parts, the hasp will be automatically cast-orf or swung away fromthe staple as soon as the latch shall have released the hasp, so thatthefastener must be either rigidly locked or absolutely tree. Hence, myinvention provides not only a 'partially automatically acting lock otsimple construction, but a lock that is to a certain extent a safetylock, as under no circumstances can the parts be partially securedtogether in a manner to deceive the operator. Having thus described theinvention, what is claimed as new is:

1. The combination with parts to be secured together, of a 'haspconnected to one of said parts, a keeper connected to the other of saidparts and arranged Jfor engagement by said hasp, an automaticallymovable latch arranged to lock the hasp to its keeper, means for holdingsaid latch in an inoperative position against its automatic movement andout of engagement with the hasp and keeper, and means for releasing saidlatch from the holding means upon the engagement of the hasp with thekeeper.

2. The combination of parts to be secured together, of a hasp secured toone of said parts, a keeper secured to the other of said parts anddesigned Jfor engagement by said hasp, an automatically movable latchadapted to lock the hasp to the keeper, a spring cast-oil arranged toswing the hasp away from the keeper, and a detent secured to and carriedby said cast-0H and provided with means for holding the latch in aninoperative position, the hasp being arranged to press the detent out ofengagement with the latch upon the movement of the hasp into engagementwith the keeper.

3. r1`he combination of parts to be secured together, of a hasp securedto one of said parts, a keeper secured to the other of said parts andarranged for engagement by said hasp, a spring latch adapted toautomatically move into engagement with said hasp and keeper to lock thesame together, a detent adapted to hold the latch in an inoperativeposition out of engagement with the hasp and keeper, and a depressiblesupport to which said detent is connected, said support being adapted tobe depressed by the movement of the hasp on the keeper, whereby torelease the detent from the latch.

4. A fastener of the character described, comprising a hasp formed witha slot, a base plate provided with a staple designed to project throughsaid slot, a spring cast-off secured at o'ne end to said base plate andhaving a tree end formed with a slot normally spaced from the base plateand through which slot said base plate projects, a detent pivotallyconnected to the free end of said cast-off and extending laterallytherefrom and formed with a shoulder spaced from the staple, and alaterally movable spring latch mounted on the base plate and 'formedwith a tongue adapted to spring into the staple over the hasp, thetongue being designed for engagement by the shoulder of the detent,whereby the latch will be held in inoperative position until the hasp ispressed over the staple upon the cast-ott so as to carry the sameinwardly towards the base plate with the detent and free the latter fromengagement with the latch.
